Measuring pathological traits of the schizotypal personality disorder through the HiTOP model.

Schizotypal personality disorder (STPD) is characterized by difficulties in intimate relationships, social and interpersonal deficits, and perceptual distortions. Encompassing this personality disorder and other mental conditions, the Hierarchical taxonomy of psychopathology (HiTOP) is an evidence-based, dimensional model covering pathological traits in its lower range. This study aimed to develop a self-report scale for screening pathological traits of STPD from the perspective of the HiTOP.
